New Technologies and Co-Products

• Ron Stover
• Merchandiser
• UBE Ingredients, LLC

2
Current Technology

• Products limited to Wet, Modified and DDGS
• Typically 36 Pro-Fat, 10-12 Moisture
• Syrup can be sold separate
• Increased ethanol production speed can cause
  incomplete fermentation resulting in burning of
  DDGS

3
Desired Changes in DDGS

• Flow ability needs to improve
• Sulfur levels have risen over the last 5 years
• Phosphorus levels from a waste management
  perspective especially ruminants
• Consistency in nutritional qualities

4
Current Changes in DDGS

• Variation among plant designs
• Genencor/Broin cold-cook technology
• Broin fiber stream removal
• Removal of corn oil for biodiesel
• Front-end fractionation for germ and fiber

5
DDGS as Fuel

• Studies have shown burning DDGS produces
  approximately 5000 btu/lb
• Translates to 10 mmbtu/ton, or 3.2 million mmbtu
  for a 100 mmgy ethanol plant
• _at_8/mmbtu Natural Gas, 3.2 million mmbtu cost
  25,600,000, equal to 80/ton ddgs
• 100 mmgy plant uses approximately 3.4 million
  mmbtu in one year if drying all co-product to
  DDGS
• Environmental Costs ?
• Initial Equipment Costs ?
• Increases food for fuel debate ?

Biomass Potential

Cellulosic Ethanol Plant Considerations- 20 mmgy
plant

• Cost of Plant is three times todays
  corn-to-ethanol plant
• Biomass must be pre-treated
• Sugars to ethanol conversion still only yields 2
  concentration of ethanol
• DOE figures biomass will be delivered for 35/ton
  but industry estimates closer to 60/ton
• Requires 79 storage facilities the size of
  football fields with 1300 lbs. square bales
  stacked 6 high
• Assuming 30 of the corn acres, and 1/3 of the
  stover per acre are collected, there will be a
  draw area of a 33 mile radius
